Those are 6.35 mm knobs. You can fit them well enough on the level/tone/etc pots (no damage or knobs falling off) but they won't be centered correctly because all those pots have 6mm D shafts: the holes in the knobs are too wide.

I bought the push-on knobs from e-licktronic but I don't like how much force I have to use to put them on. I am looking for some knobs that use set screws instead.

I am still waiting to receive 6mm set screw knobs so I am not 100% sure yet that they are the best solution.

For the instrument / mode selectors the situation is much easier: just get some 6.35mm set screw knobs you like. I ordered these: https://www.banzaimusic.com/Synth-knob-Synthie-1.html

I haven't got around to trying those yet
